متن کاملW-band waveguide bandpass filter with E-plane cut.
In this paper, we present a design and measurements of a five-section bandpass filter with a passband from 96 to 106 GHz. The insertion loss is less than 1.4 dB in the passband, and the rejection is better than 40 dB in the range from 115 to 142 GHz. We use transmission line coupling theory based on Tchebyscheff's synthesis in order to provide an initial guess for the geometrical parameters of ...
متن کاملMiniaturization of superconducting coplanar waveguide bandpass filters by cross coupling
For more size reduction of the high temperature superconducting coplanar waveguide (CPW) bandpass filter (BPF), we introduce the design method of the meanderline CPW quarter-wavelength resonator BPF. The exact admittanceand susceptance-inverters are calculated by using the 2.5-dimensional electromagnetic field simulator. The prototype YBCO miniaturized BPF (center frequency =10GHz, n=3, band wi...
متن کاملAn 11.5 W Yb:YAG planar waveguide laser fabricated via pulsed laser deposition
We present details of the homo-epitaxial growth of Yb:YAG onto a <100> oriented YAG substrate by pulsed laser deposition. Material characterization and initial laser experiments are also reported, including the demonstration of laser action from the 15 μm-thick planar waveguide generating 11.5 W of output power with a slope efficiency of 48%. This work indicates that under appropriate condition...
متن کاملYtterbium-Doped Glass Waveguide Laser Fabricated by Ion Exchange
A ytterbium-doped, glass, channel waveguide laser, fabricated by ion exchange, is reported. The 2.2-cm long device, using broad-band 4% output couplers, lased in the vicinity from 1020 to 1030 nm when pumped by a Ti : sapphire laser operating at 910 nm. A lasing threshold of 50 mW (launched pump) and a slope efficiency of 5% were measured. Device parameters, including fluorescence lifetimes, em...
